Compare The Mass Of Raisins During The Process Of Osmosis

104 Words1 Page

My hypothesis was correct. The raisins increased in mass because of the absorption of the water. The mass of the raisins before they were put in the warm water was 2.69 grams. The mass of the raisins after were put in the warm water was 3.13 grams. The mass of the raisins increased .44 grams during the process of osmosis. The water level decreased when the raisins absorbed it. Before the raisins were put in, the water level was 50mL. After the raisins sat in the water for 20 minutes and then taken out, the water level was 47mL. The water level decreased

  • Essay On The Effect Of Temperature On Osmosis

    1159 Words  | 5 Pages

    Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick   Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.

    Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.

  • Osmosis In A Potato Cell

    Osmosis Lab Report Research Question: How does the change in the concentration of a sucrose solution affect the process of osmosis in a potato cell by measuring its mass? Background information: 1 Osmosis is the process by which a liquid passes through a semi-permeable membrane, moving from an area with a high concentration of water to a low concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions can affect the rate of osmosis, as there is more difference in the concentration of the solutions, which means osmosis, will take place quicker. Surface area could affect osmosis based on the ease by which molecules can get through the semi-permeable

  • Egg In Vinegar Lab Report

    An egg naturally has a lot of stuff inside, so the outside solution has to be very concentrated for this to happen. That’s the case when an egg is treated with corn syrup or buried in salt. By contrast, when an egg is treated with distilled water, or a dilute salt solution, the solute concentration is higher inside the egg than out, so the water moves into the egg, increasing its mass. It may be easier to think about osmosis in terms of water concentration rather than solute concentration. If the solute concentration is high, then the water concentration will be low by comparison.

    The overall project goals and central questions that has to do with the project is mostly trying to determine the isotonic concentration of the salt in potato roots and the use of the ideal soil salt conditions for the potato plant growth. In part 2, we had to test the enzyme activity that is in the was involved in the potato, so we can also determine the ideal soil pH conditions for the potato plant growth. In part 3, we were able to test absorb the leaf pigment at various wavelengths that determine the optimum light absorption conditions and was able to make recommendations for the light conditions that would be used un greenhouses. The goal of the first project is to determine the ideal soil salt for potato roots and we can relate this to the project is to find out if Solution A or Solution B has more solute in it. The goal of this project is to determine the meaning of Osmosis.

  • Water Hydration Lab Report

    603 Words  | 3 Pages

    In this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up

    Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).
